To all Iwhom 'it may concern.'

Be it known that I, THOMAS M. JEWELL, a citizen of the vllIiited-States, residing at Chicago, in the county of' Cook and State of Illinois, have invented a new and useful Improvement in Guide-Boxes for Rolling- Mills, of which the following is a specification, accompanied by drawings, forming a,

part of the same, in which- Figure 1 represents in sidefeleva'tionl a 'l vertical sectional View of a pair of rolls of a rolling mill, with such portion'of the l1ous.

ing as is necessary to illustrate the natureof my invention. Fig. 2 is a'frontviewof the guide box. Fig. 3 is a vertical sectional -view of the guide box on the plane of the broken line 3-3, FigL' l.

Similar reference figuresl referto similar parts inthe different views. My present invention relates particularly to the method of mounting the guide box of a rolling mill upon its supporting bar, and it has for its objects to facilitate the adjustment of the guide box to the rolls ofthe mill,

and to .enable the guide-box to be rigidly heldin. correct alinement by the use of a single bolt which may be breakable under any undue strain upon the guide box', such for example, as that due to a cobble produced by an interruption of the movement of the metal throughthe rolls, and I" accom plish these objects by means of the construe tion as hereinafter described and set forth in the annexedl claims.

In. the accompanying drawings 1v denotes a f portion of the roll housing inwhich are I .journaled a pair of rolls Attached to the front of .the housing and extending' across fromside to side in front of the rolls 2, 3, is a guide supporting bar 4 attached at its ends by bolts to the front of the housing,

one of'which is shown at 5, Fig. 1. Theguidesupporting bar 4is provided onjits upper surface with alongitudinaligroove 6,

to receive a rib or tongue 7 uponthe under* side 'of' an intermediate plate 8. which 1s longitudinally adjustable along the bar 4.

with a groove 9 at exact right angles tothel `5o Thepla'te 8 is provided on'its upper edge rib 7- to receive a closely fitting rib 10 on'th'e under side of the guide box 11.. The guide box 11 is recessedl at 12 to receiveth'ehead 13 of a boltl 14, which passes through a slot 15V whichiis elongated in the direction of and parallel with the groove 9 of the intermediate plate 8. The bolt passes through a hole in the intermediate plate 8 and also through a slot 16 elongated in the direction of and parallel with the groove 6 upon the guide supporting bar 4. The intermediate plate 8 has itsI forward edge turned upwardly, forming a flange 17 to receive the adjusting screws-18 which are held in thev flange 17 and engagethe front of the guide box 11. f I

The guide box is secured to .the guide bar 4 by means of the bolts 14an'd nut 19, and 'the bolt may be made of such material or Size as'to furnish the requisite strength for -the permanent attachment of the guide box t'its supporting` bar 4 under any vordinary stress in the operation of the machine, but

capable of breaking under any undue strain,

thereby allowing the guidebox to be'lifted from its seat without other damage than the breaking of the bolt 142..

By loosening the nut 19 the guide box-may be adjusted along the bar 4. to the extent of the elongated slot 16, and the guide'box'- may be further. adjusted toward or away from therolls 2, 3, by sliding'the" guide box upon thein'tervening plate 8 and `an accurate adjustment of the guide box toward the'rollsis secured by means of the adjusting screws 18. When theA nut 19 is tightcned', the guide box-11, intermediate plateV 8 and bar-4 areheldin -frictional contact, and the grooves. 6 and' 9 determine the cor'- rectangular adjustment of the guide box witlirelation to the circumferential grooves orpasses of the rolls. The guide box may be 4adjl'ls'ted.both parallel with4 and at right .ar-iglesjto the' axes ofthe rolls by merely loosening. thefnut 19 on the bolt 14, which forms the only connection between the guide boxandthe supporting bar. .'Vifheneverlthe nut 19 is slightly loosened the guide box is .still held in true angular relation to the rolls` byv thei"*i`nterlocking grooves and ribs, as abovedeseiihed.

l Thep'resent drawing shows in Fig. 1 a receiving guidebox for conducting a metal rod to the roll. The same construction of intermediate plate and supporting bar may be employed inthe case of a delivery guide /Iu box-for conducting a metal rod from the rolls and in this case, since the strain is outward, it is received by the adjusting screws i8 vand transferred to the intermediate plate 8 which is held against the outer shoulder of the groove 6.

I claim, j 1. The combination with a pair of rolls, of

a guide supporting bar., a guide box sup# ported by said bar, an intermediate member between said guide box and said bar, said intermediate member arranged to be adjustable on sa'id bar parallel with the axes of, said rolls and said guide box arranged i to be adjustable on said intermediate' mem;-

- ber at right angles to the axes of said rolls,

and means extending between said guide box and said bar for holding said guide box, said intermediate member and saidl bar in frictional contact.

2. The combination with a pair of rolls, of

a guide supporting bar having' a groove parallel with the axes of said' rolls, a guide box supported by saidbar, an intermediate plate between said guide box and said bar,

said plate'having a rib or tongue arranged' to engage the groove on said bar and alsomeans-for maintaining said guide box While infcontaet"withsaid intermediate member inga 'lirici-at right angles to the axes of'said rolls, means for maintaining said intermediate member while inI contact with said bar in a line parallel with the axes of said rolls,

" and adjustable means connecting said guide box and said bar arranged to hold said' guide box, said'intermediatev member and said bar in rictional contact. f

4. The combination with'a pair of rolls, of a 'guide supporting-bar, a guide box sup- 'v ported on saidbar, an intermediate memsaidguide box may befmoved both parallel er between' said guide box' and said bar,

said intermediate member arranged to be adjustable. on said bar and said guide box jarrangedw'to'vbe adjustable on said inter- #mediate member, wherebythe' opening in with and at right angles to the axes of said rolls, and a single member 'arranged to hold and said bar in frictional contact, said memsaid guide box, said intermediatemember ber capable of breaking under `an undue strain, thereby releasing said guide box from said supporting bar. v

.5, The combination with a pair of rolls, of

va guide supporting bar, a guide box supported by said `bar, an intermediate member between said guide box and said bar,

said intermediate member arranged Ito be' adjustable on 'said bar and said guide box arranged to be adjustable on said intermediate member, whereby the .opening in said guide-box may bemoved both parallel with and at right angles to the axes of said rolls,

and a bolt connecting said guide box and sald bar,passing through said intermediate member.

6. The combination with a pair of rolls, ofv

`a guide supporting' bar, a guide box supported by said bar, an intermediate memberbetween said guide box and said bar, said intermediate member arranged to be adjustable on said bar and said guide box arranged to be adjustable on said lntermedi- -ate member, whereby 'the opening in said guide box may be moved both parallel with and at' right angles to the axes of said rolls,

,and adjustable means extending between said guide box and said bar for holding said guide box, said intermediate member and said bar in frictional contact.

7 .Tl1e combination with a pair of rolls, of a guide supporti-ng bar, a guide box supportedv by said bar, an intermediate memf' ber between said guide box and said bar, said'supporting bar" having a groove parallel with the axes of the rolls, a rib or tongue on said intermediate' member fitting` said groove, an upturned-flange on saidinter` mediate member having. adjusting screws bearmg against said guide box,`said intermediate member also.' having a groovel at right angles with the axes of said rolls,

and a rib or tongue on said lguide box fitting said groove on said intermediate member. Dated this 26th .dayA of` ()ctober 1908.
